    The essentials of insulated case circuit breakers

    Insulated case circuit breakers, or ICCB’s, are essentially molded case circuit breakers with an integral 2-step stored-energy mechanism, and are available at much higher amp ratings. Molded case circuit breakers frame sizes range from 100-1200 amps, while insulated case circuit breaker frame sizes range from 800-5000 amps. Due to their higher ampere ratings, it’s not uncommon to replace an old air circuit breaker with an insulated case circuit breaker, if the situation allows. However, unlike an air breaker, an insulated case circuit breaker is fully contained in its case, so it cannot be opened up.

    Insulated case circuit breakers and their uses

    Insulated case circuit breakers use special types of insulating material and are most commonly used across low voltage industrial applications. They are available in both fixed-mount and draw-out models. Other advantages of insulated case breakers include their size and their relatively lower cost. Insulated case breakers also have no metal on their breaker frame, and are sometimes referred to as plastic breakers.
